I've tried several different lots of corbon .32acp ammo. The first batch was useless as the rim was too big in diamenter to feed from the mag. The second batch is too erratic. I had one failure to extract (partial extraction). Upon examination of the case is noticed significant bulging which caused the round to want to stick in the chamber. I've shot with great success their .38 special rounds and they have proven very potent, but I cannot trust their .32 ammo anymore. Too bad as their round has good potential if they could make it work. I know the chambers in the p32's are oversized and I think this combined with the excessive pressure is a bad combination. I'm going to shoot the rest of the .32 corbon in both my p32's to see if I have any more problems. In the meantime, depending on the circumstances will either use win. silvertip or newly acquired Geco ammo, or s & b or fiochi.
